671s in an 11 meter

JuiceClark · Post by **JuiceClark** » Sat Dec 13, 2008 9:43 pm

Here's a nice looking 11 meter for sale in Miami. Says it has 671s. I can buy a tired 671 for $4k and know a guy who can rebuild it for $1k parts and $1.5K labor. My point is they're so cheap that I wish those Detroits would fit in an F-36....don't know how they're shoehorned into an 11 meter:

I'm confused. The ad says 11 meter Trojan and then states the length as 38 feet. I thought a meter was about 39 inches??? Anyway, the engines would be a liability to the sale not an asset. These are not your old naturally aspirated 671's that put out 160 HP and ran forever. These beasts weigh almost a ton each, burn 36 gallons an hour each at cruise, and are so souped up just a little wear and drop in compression will make them un-startable unless they're warm. 671's were a great engine in their day, but they are now obsolete and it's probably wise to steer clear of them unless they are in in a trawler.

Tony,

In the 11 Meter, the 671 engines are TILTED sa bit to allowfor the engine height to fit.

PRices on all older boats have been falling lika a rock. I saw a pristine 14 meter, really nice detailled pictures on line for just $99,000.

UNBELIEVEABLE!

ANyone looking for an older boat has to be willing and capable of handling more major repairs than someone looking at a 10 year old Searay, thus narrowing the already diminished market considerably.

Tony, what's the status of your ambitious boatbuilding saga?

Danny , there not as bad on fuel as you think My frends viking with 2 of those 671s at 450 hp each may burn close to 30gph total at cruse . He gets .7 mpg average I can find out exatly when I talk to him next .

I think the 11 meter was 37.5 feet per C.G. doc. on 2 I checked .the 12 meter a 40 footer The beam on the 11 was 14 foot not 13 like the add said.

Reelfishing has a 11 meter with the 671s ( 450 hp I belive )

Juice I don't think you could find a 450 hp 671 for that cheap and don't think you will get it redone that cheap. 1500 per hole up is the going rate .
the parts for the high output maybe cost more then the low output .

But then again you seem to find deals

The add said these had been recently gone through but anyone considering buying should get 'em surveyed. My son was looking at a 36 Hatteras last spring with two 390 HP 671's in it and asked me to be there for the engine survey. I was amazed at how much the surveyor knew about 671's, how thorough his inspection was, how much stuff he found wrong and how much he said it would cost to fix. The compression was just below minimum on about half the cylinders and the stbd engine almost would not even start...spin, smoke, poomp poomp poomp for awhile and finally start with enough smoke to hide a battleship. I lost a lot of faith in turboed and aftercooled 671's that day and no, he didn't buy the boat.

I like them but at 450hp they are a 2000 hour engine even thou I know one boat with ove 4000 hours on a set and the still run great . but have seen them worn out at 1800 hours . normally at 400 hp and below the do well at 300 hp and below they are hard to kill .

We have the 671's in our 11 meter Trojan. The secret to keeping the engine in good shape is maintance and running them. If you leave the boat sit a lot then you are headed for trouble. Ours do not smoke at start up and run like a top. We have diesel mechanic who comes twice a year and changes the oil and checks the engines over.
I will admit we had our engines completely rebuilt from the bottom up. The mechanic insisted on OEM parts and not remanufactured parts. It really was a professional job.
We also believe in block heaters. I believe there are two sizes of block heaters. One keeps the engines at 140 degrees and the other around 90 degrees. We use the 90 degree ones. They work just fine and our engines do start with out smoke. We use the block heaters year round.
Yes the 11 meter is 14 feet wide and it does make a big difference in handling and riding on the ocean. We can turn that boat around on itself.
Idle speed is around 6 knots and cruise speed is around 22knots.

24 feet wide ? I bet you mean 14 . Got to love block heaters

Prowlerfish, Yep those heaters really do a job on a boat. LOL Thanks for catching it.

450hp? Prowler, If I had 450hp Detroits in my boat, with all that torque, the thing would be a rocket wouldn't it? I was thinking more about a pair tuned down to 250hp or so. I'd think that would be a 23k boat?

But the whole conversation is pointless I guess anyway. My 454s touch the salon floor so 671s would be end up being salon furniture. This is close to the prices I've seen:

Well, the molds are done for everything but the flybridge and helm. So, the investment has been made. But the plant has been quiet for a month.

Our two buyers are delaying....say they're freaked out by the economy. Both have more money than they could spend in 5 lifetimes, but one is just dragging along and the other says he wants to make sure this is a "recession" and not a "depression" before we start the hull. Can't blame him really...just being careful with chronic bad news everywhere.
Such is the way. I always tell my wife we should buy a funeral home because then nobody would ever die!

I've had some action from newly interested parties in the last week though. Funny, when I told some friends with exposure to wealthy boat lovers that I'd give them $40,000 if they brought a buyer of our hand-built, totally customized boat - all of a sudden the phone started ringing!

The deals we have right now from MTU and Iveco and are really significant. I mean, we're talking $60k for a 770hp Iveco...which we really like better than MTU, CAT or Cummins of the same size. Plus, buying the glass for 1/2 off wholesale, glass layers with a lot of experience and no work right now plus deals on whatever else means we can really cut the manufacturing cost to the bone. Even yacht interior decorators are damned near free. For a boat that Viking or Cabo would want $1.8 million +, I think we'd do fine for under a million bucks. If somebody wants a yacht (or real estate, or a stock portfolio, etc., etc.), now is certainly the time!

We're just gonna kick back and wait for someone to write a lil' check and say "go!" No spec boats for this investor...and you can't sell a boat as custom anyway before the buyer shows up!

Tony you know you want a set of cummins B s they weight half want a 671 would .

Hell yes I do...but the wife currently has the upper hand!

With all the new technology out there in engines I would be enclined to go with a newer motor than the 671's. Why? Fuel savings, ease of maintenance. I think some real research would be my way of doing it. Finding out which engine would perform the best and have longevity.

Now looking at the picture of the boat. It really is a nice boat. Here is my thoughts when I go on a boats flybridge. Can I see the cockpit?
Can I see the bow? All from the captain seat. Fishing you need to see the cockpit for sure. Docking you need to see the stern and the bow.
Next thing is the width of the boat. I would not have anything less than a 14 foot wide boat. Handling improves quite a bit over a 12 foot wide boat and the inside gives a lot more room.
One thing the boating industry has not been able to do I think is close the flybridge in with glass. No canvas. I think it could be done just have not figured it out yet. LOL

reelfishin Just go down to Blue water they have the enclosed fly brige you want with heat and a/c . BTW bring a Million or so with you for the down payment.
